Blue Hour palette
Emerald Crater
Five stops tuned to sit together without fighting — #005882 ink anchors the set, #84c9f8 opens it up, and #2882b5, #489ed2, #67adda cross the middle in a monochromatic arrangement. Emerald Crater suits national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
